The Ripagreen uses hot air to kill plants. This method is suitable to use in a much wider variety of weather than many other systems.
The hot air is not affected by drift in the same way chemicals are, so the Ripagreen can be used in moderately windy conditions, provided the flame can be safely controlled.
The Ripagreen is just as effective at killing the plant in the rain, as moisture is a good conductor of heat. The ripagreen operates at temperatures of between 400 - 600 degrees celsius, so it is not largely affected by cold or wet weather.
This makes is a reliable tool for year - round use.
Care should be taken on very hot and dry days, as the heat can cause very dry maerial to catch fire. It is good practice to carry a fire extinguisher when using the Ripagreen and other flame or heat based weed control products.
